not sure that you can do that but you can open the windows registry "regedit" with the jshell library

This library will store the settings in the registry: http://www.b4x.com/android/forum/threads/jslpreferences-library.35336/#content

Can you post this in SLPreferences Library thread and post some more code, showing where and how you stored the preference in the first place.
